Solution steps

Find undefined (singularity) points:

x = 9

The function domain

x < 9 or x > 9

Popular Examples

domain of 2cos(x)-sin(2x)domain

2 cos (x) - sin (2 x)

domain of f(t)=-3t domain

f (t) = - 3 t

domain of sqrt(1-2^t)domain

1 - 2^{t}

domain of f(x)=6-3/(x^5)domain

f (x) = 6 - \frac{3}{x ^{5}}

domain of f(x)=((x^2-3x))/(x^2-9)domain

f (x) = \frac{( x ^{2} - 3 x )}{x ^{2} - 9}
